When your air conditioner is fresh and running properly, it’s not normal to be smelling anything weird. Abnormal air conditioner noises and odd smells are a hint that something is off. If your air conditioner is aging or you haven’t had a tune-up completed recently, they can be an obvious sign you need pro air conditioning repair in Libertyville.

Here are six of the top air conditioner smells and how you can repair them.

1. Central Air Conditioner Smells Like Chemicals

If your air conditioner smells bad when turned on, specifically a chemical scent, it isn’t a great sign. You might also report your:

  • Air conditioner smells like paint thinner
  • Home air conditioner smells sweet

These sweet, chemical odors are frequently a hint that your air conditioner is suffering from a refrigerant leak. Your system relies on this gas to transfer heat through copper coils, which can wear out as time passes.

Four clues you are dealing with a refrigerant leak.

Besides the odd smell, here are four other signs that you have a refrigerant leak.

  1. Bubbling or hissing sounds when your air conditioner is on.
  2. Ice on refrigerant lines or the evaporator coil.
  3. Trouble keeping your house cool or achieving your desired temperature.
  4. High energy expenses.

How You Can Fix It

A refrigerant leak requires skilled support from a heating and cooling company like TopTec. Your cooling pro will locate and repair the leak before recharging your system with refrigerant.

Resolving a refrigerant leak typically costs between $225 and $1,600, based on nationwide averages compiled by HomeAdvisor. Your total cost will depend on the location and severity of the leak, as well as how long it requires to fix.

If your air conditioner was installed early than 2010, there’s a high probability it uses R-22 or Freon refrigerant. This refrigerant is no longer being made as a result of its negative effects on the ozone layer. Consequently, repairs can be extremely expensive so it may be wisest to schedule air conditioning installation in this situation.

2. Air Conditioner Smells Like Gas

If your air conditioner smells like rotten eggs, there’s likely nothing wrong with it. But there’s a high likelihood you have a natural gas leak in your residence. Natural gas has a sulfur-like additive to signal you when there’s a leak, as the gas can be toxic in large amounts.

How You Can Fix It

If you detect a sulfur or rotten egg odor, we advise:

  • Shutting off your gas supply.
  • Opening windows.
  • Going outside promptly.
  • Getting in touch with your gas company without delay.

3. Air Conditioner Smells Musty

Homeowners who contact us about this problem often report their air conditioner smells like feet, dirty socks or a locker room when it runs. Also known as dirty sock syndrome, this smell is usually caused by a grubby evaporator coil that has mold, mildew and bacteria buildup. Excess water can also make your home air conditioner smell bad. Dirty sock syndrome is most often seen in locations where you use heating at night and during the morning before switching to cooling later in the day.

How to Repair It

The best method for preventing dirty sock syndrome is to regularly replace your air filter and schedule regular air conditioning maintenance with TopTec. We’ll keep the evaporator coil clean and the drainage system flowing, as excess water can also produce noxious odors.

4. Air Conditioner Smells Like Vinegar

If you are experiencing air conditioner mildew smell or a pungent, vinegar-like odor, it can be caused by several situations, like:

  • A filthy filter
  • Extra condensation
  • Blocked condensate pan or drain line
  • Moldy air conditioner or ductwork

How to Resolve It

Inspect your filter first. If you haven’t changed it within the last three months and can’t see light through it, it’s time to replace it. If that doesn’t resolve the problem, contact TopTec at 847-362-0262.

5. Air Conditioner Smells Like Burning Plastic

If you’re experiencing an air conditioner burning smell or that your air conditioner smells like fish, there could be a number of things wrong. These include:

  • Broken capacitator that’s overheating the motor.
  • Motor that needs lubrication.
  • Broken fan belt.
  • Electrical trouble.

Electrical issues should be examined immediately to avoid a fire. If you detect burning plastic when your air conditioner is operating, shut it off and call us at 847-362-0262 immediately.

6. Air Conditioner Smells Like Cat Pee

A powerful ammonia odor means there may be mold present within your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold creates.

How to Solve It

Mycotoxins are hazardous to your well-being. That’s why we recommend having a professional like TopTec examine your air conditioner and ductwork and clean it when necessary.
